MOS Transistors: What Textbooks and SPICE Tell You is Wrong
CMOS Circuit Design
Abstract:
Design of analog CMOS circuits requires a proper understanding of how MOS transistors work. Almost all design textbooks present incorrect small-signal models for MOS transistors. They emphasize Cgd, which for the intrinsic transistor is negligible in saturation, and completely ignore Cdg, which is the 2nd largest capacitance in saturation (where most MOS transistors in analog circuits operate).
What is the difference between Cgd and Cdg?
Why is the most important of these in saturation not Miller multiplied?
Why are the gm and VDsat values that SPICE tells you are wrong?
Find out in this talk.

Biography:
Biography: Colin McAndrew received the Ph.D. degree in systems design engineering from the University of Waterloo, Canada. He was at AT&T Bell Laboratories for 7 years, and since 1995 has been with NXP, where he is a Fellow of Technical Staff. He is a Fellow of the IEEE, was an editor of the IEEE Transactions on Electron Devices from 2001 to 2010 and an editor of the IEEE Journal of the Electron Devices Society from 2013 to 2022. He is or has been on the technical program committees for the IEEE BCTM, ICMTS, CICC, and BMAS conferences. He received best paper awards from ICMTS in 1993 and 2012, CICC in 2002, and BCTM in 2015. He has published more than 130 refereed journal and conference papers, 10 book chapters, and one book, and given numerous invited papers and short courses at leading industry conferences.
